I was able to figure out the answer. http://forums.adobe.com/message/5112560#5112560
This is what was wrong. It was because the executing code was in a loop and I wasn't allocating strings with the new operator.
This was the line that needed a new on it. wchar_t footagePath[AEGP_MAX_PATH_SIZE];
Another piece of information that would have been useful to know is that not ALL footage items have paths.
If the don't have a path it will return empty string. This is the code I ended up with.
if (itemType == AEGP_ItemType_FOOTAGE) {
A_char* newItemName = new A_char[AEGP_MAX_ITEM_NAME_SIZE];
ERR(suites.ItemSuite6()->AEGP_GetItemName(newItemH, newItemName));
AEGP_MemHandle nameH = NULL;
AEGP_FootageH footageH = NULL;
char* footagePathStr = new char[AEGP_MAX_PATH_SIZE];
ERR(suites.FootageSuite5()->AEGP_GetMainFootageFromItem(newItemH, &footageH));
if (footageH) {
suites.FootageSuite5()->AEGP_ GetFootagePath(footageH, 0, AEGP_FOOTAGE_MAIN_FILE_INDEX, &nameH);
if(nameH) {
tries++;
AEGP_MemSize size = 0;
A_UTF16Char *nameP = NULL;
suites.MemorySuite1()->AEGP_GetMemHandleSize(nameH, &size);
suites.MemorySuite1()->AEGP_LockMemHandle(nameH, (void **)&nameP);
std::wstring test = L"HELLO";
std::string output;
int len = WideCharToMultiByte(CP_OEMCP, 0, (LPCWSTR)nameP, -1, NULL, 0, NULL, NULL);
if (len > 1) {
footagePathStr = new char[len];
int len2 = WideCharToMultiByte(CP_OEMCP, 0, (LPCWSTR)nameP, -1, footagePathStr, len, NULL, NULL);
ERR(suites.MemorySuite1()->AEGP_UnlockMemHandle(nameH));
suites.MemorySuite1()->AEGP_FreeMemHandle(nameH);
}
}
}
}
